In the upper part, a plurality of balls 7, preferably 10 to 20 balls are arranged and mounted in a line. Each of the balls 7 has a structure that can freely rotate in any direction. For example, when 5 kgf / cm 2 of compressed air is supplied, the engraving mold 8 placed on the ball 7 receives the compressed air. It can withstand loads up to 160 kg. Viton (a general name for fluorine-based synthetic rubber) is used as the material of the mold carrier 5 having such a function so that it can withstand the temperature of 100 to 180 ° C. at which silicone rubber can be vulcanized. Is preferred. When the die carrier 5 is supplied with compressed air and the engraving die 8 is raised, the bottom surface thereof is lifted by 2 to 3 mm from the lower heating plate 4, and the engraving is stopped when the compressed air supply is stopped. The height is such that the bottom surface of the mold 8 can be brought into close contact with the lower heating plate 4.

【0007】 彫り込み金型8は圧縮空気の供給を受けて金型搬送器5の高さが上昇したとき に、両側下面を上記左右のボール7‥の列に支持されて、遮光性部分成形用浮き 出し金型2と透光性部分成形用浮き出し金型3の下方間を反復移動できるように 設けられている。なお、この金型の反復移動方法には、1)シリンダーにより金 型を前後に移動する方法、2)左右のボールの代わりに回転ローラを用いてロー ラの回転で金型を前後に移動する方法などがある。 9‥、10‥はそれぞれこの移動範囲を制約するために下部熱板4の両側に植設 された位置決めピン、11‥、12‥はそれぞれ位置決めピン9‥、10‥と嵌合して 彫り込み金型8を位置決め・固定するために、その両側に設けられた固定用切り 欠きである。 また、13‥は金型搬送器5に圧縮空気を供給して彫り込み金型8を2〜3mm上 昇させたときに、この位置に彫り込み金型8を両側から保持・固定するためのボ ールプランジャー、14‥はこれを係止するために彫り込み金型8の先端部両側に 設けられた固定用切り欠きである。 ボールプランジャー13のボールは1.9kgfの荷重で沈み始め、5kgf の荷重で1 〜2mm変位するような強さのスプリングで押さえ付けられている。ボールプラン ジャー13はまた、図4および図8に示されるように、金型搬送器5に圧縮空気が 供給されて彫り込み金型8が下部熱板4より浮いた状態では、彫り込み金型8に 設けられた固定用切り欠き14から外れ、金型搬送器5への圧縮空気の供給が停止 されて彫り込み金型8が下部熱板4に密着した状態では、固定用切り欠き14に嵌 る高さに取り付けられている。 なお、図1および図2における、15は油圧プレス、16‥は支柱、17‥はヒータ ーである。The engraving die 8 is supported by the row of balls 7 on the left and right sides to support the light-shielding partial molding when the height of the die carrier 5 is raised by receiving the supply of compressed air. It is provided so that it can be repeatedly moved between the lower part of the embossing die 2 and the embossing die 3 for translucent partial molding. In addition, the method of repeatedly moving the mold includes 1) a method of moving the mold back and forth by a cylinder, and 2) using a rotating roller instead of the left and right balls to move the mold back and forth by rotating the roller. There are ways. 9 and 10 are positioning pins implanted on both sides of the lower heating plate 4 in order to limit the movement range, and 11 and 12 are fitted with the positioning pins 9 and 10, respectively, and the engraved metal Fixing notches are provided on both sides of the die 8 for positioning and fixing the die 8. Further, 13 is a ball plunger for holding and fixing the engraving die 8 from both sides at this position when the engraving die 8 is raised by 2 to 3 mm by supplying compressed air to the die carrier 5. , 14 are notches for fixing which are provided on both sides of the tip of the engraving die 8 for locking them. The ball of the ball plunger 13 begins to sink under a load of 1.9 kgf and is pressed by a spring having a strength such that it is displaced by 1 to 2 mm under a load of 5 kgf. As shown in FIGS. 4 and 8, the ball plunger 13 also moves to the engraving die 8 when the engraving die 8 floats above the lower hot plate 4 by supplying compressed air to the die carrier 5.

【作用】[Action]

つぎに、上記照光式押しボタンスイッチ用カバー部材の成形用金型の作用につ いて説明する。 まず、型締め装置の上部熱板1に一体金型である遮光性部分成形用浮き出し金 型2と透光性部分成形用浮き出し金型3を装着すると共に、下部熱板4の金型搬 送器5上に彫り込み金型8を装着する。 彫り込み金型8は、例えばシリンダー方式、回転ローラ方式など(図示せず) によって、金型搬送器5上を遮光性部分成形用浮き出し金型2の下方に移動させ 、図2に示すように彫り込み金型8の固定用切り欠き11‥に位置決めピン9を嵌 合させることで、彫り込み金型8を位置決め固定する。また図3(a)および図 4に示すように、彫り込み金型8の固定用切り欠き14にボールプランジャー13の 先端を挿入することで、彫り込み金型8を固定し下部熱板4に密着した状態とす る。 この彫り込み金型8は下部熱板4によって、また遮光性部分成形用浮き出し金 型2および透光性部分成形用浮き出し金型3は上部熱板1によって、それぞれ 1 00〜 130℃に加熱されている。この状態で彫り込み金型8に遮光性部分成形用液 状シリコーンゴムをディスペンサー(図示せず)により所定量吐出・充填した後 、型締め装置により図5および図6に示すように型締めする。 100〜 140秒間、 この状態を保持してシリコーンゴムを加硫させ、遮光性部分を得る。 Next, the operation of the molding die for the cover member for the illuminated push-button switch will be described. First, the light-shielding partial molding embossing mold 2 and the translucent partial molding embossing mold 3 which are integrated molds are attached to the upper heating plate 1 of the mold clamping device, and the lower heating plate 4 is transported to the mold. The engraving die 8 is mounted on the vessel 5. The engraving die 8 is moved to a position below the light-shielding partial molding embossing die 2 on the die carrier 5 by, for example, a cylinder method, a rotating roller method (not shown), and the engraving die 8 is engraved as shown in FIG. The engraving die 8 is positioned and fixed by fitting the positioning pin 9 into the fixing notch 11 of the die 8. Further, as shown in FIGS. 3 (a) and 4, by inserting the tip of the ball plunger 13 into the fixing notch 14 of the engraving die 8, the engraving die 8 is fixed and adheres to the lower heating plate 4. The condition is The engraving mold 8 is heated to 100 to 130 ° C. by the lower heating plate 4, and the light-shielding partial molding embossing mold 2 and the translucent partial molding embossing mold 3 are heated to 100 to 130 ° C., respectively. There is. In this state, the engraving die 8 is discharged and filled with a predetermined amount of liquid silicone rubber for light-shielding partial molding by a dispenser (not shown), and then the die is clamped by a die clamping device as shown in FIGS. 5 and 6. While maintaining this state for 100 to 140 seconds, the silicone rubber is vulcanized to obtain a light-shielding portion.

【0009】 遮光性部分成形用浮き出し金型2と透光性部分成形用浮き出し金型3とは予め 離型処理が施されているので、開型後、得られた成形品は彫り込み金型8内に取 り残される。そこで、彫り込み金型8内の成形品の上から、さらに透光性部分成 形用液状シリコーンゴムを所定量、注入・充填し、金型搬送器5にシリンダー6 から圧縮空気を供給して、彫り込み金型8が図7(a)に示すように下熱板4か ら2〜3mm浮いた状態にする。このとき、ボールプランジャー13は図8に示すよ うに彫り込み金型8の固定用切り欠き14から外れるので、彫り込み金型8は金型 搬送器5上を自由にスライドできる状態となる。 この状態で彫り込み金型8を図示しない機構により金型搬送器5上を透光性部 分成形用浮き出し金型3側へスライドさせ、固定用切り欠き12を位置決めピン10 と嵌合させて位置決めする。つぎに金型搬送器5への圧縮空気の供給を停止し、 彫り込み金型8を下部熱板4に密着させ、図4に示すように再びボールプランジ ャー13の先端を固定用切り欠き14に挿入することで彫り込み金型8を固定する。 そこで型締め装置により図9および図10に示すように型締めする。 100〜 140 秒間、この状態を保持して透光性部分成形用液状シリコーンゴムを加硫させると 、目的の照光式押しボタンスイッチ用カバー部材が得られる。 なお、照光式押しボタンスイッチ用カバー部材の着色層の形成は、遮光性部分 を成形後、それぞれに着色された液状シリコーン原料を着色層の必要な厚さに吐 出注入し、加硫硬化すればよい。Since the light-shielding partial molding embossing mold 2 and the light-transmitting partial molding embossing mold 3 have been subjected to a mold release treatment in advance, the molded product obtained after the mold opening is the engraving mold 8 Left behind. Therefore, a predetermined amount of translucent liquid silicone rubber for partial molding is injected and filled from above the molded product in the engraving mold 8, and compressed air is supplied from the cylinder 6 to the mold carrier 5. As shown in FIG. 7A, the engraving die 8 is set so as to float from the lower heating plate 4 by 2 to 3 mm. At this time, the ball plunger 13 is disengaged from the fixing notch 14 of the engraving die 8 as shown in FIG. 8, so that the engraving die 8 can freely slide on the die carrier 5. In this state, the engraving die 8 is slid on the die carrier 5 by the mechanism (not shown) to the embossing die 3 side for forming the transparent portion, and the fixing notch 12 is fitted with the positioning pin 10 for positioning. To do. Next, the supply of compressed air to the die carrier 5 is stopped, the engraving die 8 is brought into close contact with the lower heating plate 4, and the tip of the ball plunger 13 is again made into the fixing notch 14 as shown in FIG. The engraving die 8 is fixed by inserting it. Therefore, the mold is clamped by the mold clamping device as shown in FIGS. 9 and 10. By keeping this state for 100 to 140 seconds to vulcanize the translucent liquid silicone rubber for partial molding, the target cover member for the illuminated push-button switch can be obtained. The colored layer of the cover member for the illuminated push-button switch is formed by molding the light-shielding portion, then injecting each colored liquid silicone raw material to the required thickness of the colored layer, and vulcanizing and curing. Good.

【0010】 本考案の成形用金型では原則としてすべて液状シリコーンゴムを使用して成形 する。液状シリコーンゴムのため各原料を2層ないし3層の積層状態で成形する ことができない。これは各原料が混合せず、本来成形すべき遮光部、着色部、透 光部がそれぞれ成形できないためである。また遮光部23ではできるだけ薄く均一 に成形するのが望ましく、着色部26において光を透光し均一にムラなく輝度が落 ちないように成形するには、厚さを均一にしかも気泡が入らないようにする必要 から、とくに低粘度の液状シリコーンゴムが用いられる。このように各層の機能 を十分満足させるために原料毎の注入方式で行う。In principle, the molding die of the present invention is molded using liquid silicone rubber. Since it is a liquid silicone rubber, each raw material cannot be molded in a laminated state of two or three layers. This is because the raw materials are not mixed and the light-shielding portion, the colored portion, and the light-transmitting portion that should be originally molded cannot be molded. Further, it is desirable that the light-shielding portion 23 is formed as thinly and uniformly as possible, and in order to form the colored portion 26 so that light is transmitted and the luminance is not evenly reduced, the thickness is uniform and bubbles are not formed. For this reason, a liquid silicone rubber having a particularly low viscosity is used. In this way, the injection method is used for each raw material in order to fully satisfy the function of each layer.

【考案の効果】[Effect of device]

本考案の成形用金型によれば、1ショットごとの浮き出し金型取り替え作業が なくなり格段に作業効率が向上するほか、1台の型締め装置で全工程が行われ、 型締め装置に取り付けられていない浮き出し金型の加熱装置も不要になり、製造 コストが低減される。また、 100〜 180℃に昇温された金型の取り回しがなくな ったことで作業者の安全が一層確保される。 According to the molding die of the present invention, the work of exchanging the embossing die for each shot is eliminated, and the work efficiency is remarkably improved. In addition, all the steps are performed by one die clamping device and the die is attached to the die clamping device. It also eliminates the need for a heating device for the raised die, which reduces manufacturing costs. In addition, the safety of workers is further ensured by eliminating the need for handling molds heated to 100-180 ℃.
